The philosophy
Every scale tone has an emotional signature. A 4th feels unresolved. A major 7th feels yearning. A flatted 3rd feels blue. Most musicians play these notes their whole lives without ever hearing what they actually mean. That's what jAMSKOOL is for — six apps, each a different angle on the same idea: music is something you feel, and knowing what choices to make to evoke a particular feeling, instead of stumbling on them by accident, makes you a better musician.
Video Series
A YouTube series exploring the esoteric side of hearing music properly — the hidden logic behind why music makes you feel what it makes you feel. For musicians and curious non-musicians alike.
